I'm filling out registration papers for the FAA, and I have a question
 for all of you already flying.  The "Affidavit of Ownership . . ."
 asks for the "Type of Engine Installed (reciprocating, turbopropeller,
 etc)".  What have you guys been putting in this field?

 How 'bout BADASS Rotary Engine.

 This problem has come up before.
 When I get a chance I'll search the messages for what other people are
 doing.

 I am reasonably sure you enter "reciprocating".  For powerplant
 certification there are but 2 categories, recip and turbine.
 I think there was a notice to the effect that rotaries were
 considered reciprocating - the logic of rules!

 As Paul once suggested, I put non-reciprocating, intermittent internal
 combustion.  The FAA corrected me as well and put "piston" if I recall
 correctly...

 Get the idea?... they just want the general idea.  Not turboprop,
 not jet,
 not rocket.

 The form has "etc" after the two categories so I
 put "rotary" and they did not object. This was
 in August 2005. Maybe things have changed?

I went ahead and put "Wankel Rotary".  I'll let you know what happens.

Hopefully the FAA will add the category.
Sort of official recognition.

I used "Reciprocating" and it worked for me.

One would think the FAA might want to gather crash history data :)
